If you want to use the Apple Midi service, youre probably going need to code it from their spec

If you search this forum, you will find people have already investigated using the uart service but changing it to use Apple's 128 bit service ID for their proprietary Midi service / profile

OK i found this UUID on example ble_app_uart and i changed it to one of the Apple's UUID. But not work,

#define NUS_BASE_UUID                  {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x00, 0x00, 0x40, 0x6E}} /**< Used vendor specific UUID. */
#define NUS_BASE_UUID                  {{0x77, 0x72, 0xE5, 0xDB, 0x38, 0x68, 0x41, 0x12, 0xA1, 0xA9, 0xF2, 0x66, 0x9D, 0x10, 0x6B, 0xF3}} /**< MIDI I/O Characteristic */
#define NUS_BASE_UUID                  {{0x03, 0xB8, 0x0E, 0x5A, 0xED, 0xE8, 0x4B, 0x33, 0xA7, 0x51, 0x6C, 0xE3, 0x4E, 0xC4, 0xC7, 0x00}} /**< MIDI Service */

I think this Need more changes on the source.
